Special Containment Procedures: SCP-XXXX-2 should be held on-site █████ while SCP-XXXX-3 should be kept on site ████ both should be in a freezer like room.If SCP-XXXX-2 or SCP-XXXX-3 were to escape a team of 6 level 4 or higher guards are to be sent out immediately with cryo guns.

Description: The foundation located these two after reports of two large reptilian creatures were found in melting glaciers on the opposite sides of the world went on a rampage when it broke out of the ice.
SCPredacted is a large quadrupedal reptilian species that are an underground dwelling that seemed to have died out due to the ice age but 2 living members of its species have been found. These species show sexually dimorphic. with these similar traits between the male and females of the species. They are highly aggressive territorial apex predator devouring everything in their path they are an omnivore but they will choose meat over vegetation. They have large spike running down their back that is used to hold and store preserved food. it can produce a saliva that is a fast acting paralytic/poison. they can produce a fiber-like substance that can halt the decaying process. they have a prehensile tail that helps it store the food that is has preserved into its spikes. It has a bite pressure of over 500,000 psi.it is primarily nocturnal.They have webbed claws that help them swim. They can survive extreme heat and pressure but they are very vulnerable to the cold.they will enter a hibernation-like state after 3 months of food and water they will also enter this state from extreme coldness.SCP-XXXX-2 is the male version of their species it is larger and more aggressive then SCP-XXXX-3 it's female counterpart SCP-XXXX-2 can be distinguished but it's large red stripe going down it's back. SCP-XXXX-3 is the female counterpart to SCP-XXXX-2 it is smaller than its male counterpart with more of a darker covering with a greenish blue stripe going down its back. it is also more docile then it's male counterpart but that is not a reason to not be cautious around SCP-XXXX-3.every year both SCP-XXXX-2 and SCP-XXXX-3 emit a sound every 50 years that each of them can hear and after they will enter a frenzy for 3 weeks destroying anything that gets from finding their mate and they will ignore food and water once they fill their spikes on their back.Addendum: Incidents involving SCP-████-2.Incident ████-2-A

SCP involved: SCP-████-2Location:Description: On ██-██-████ Our lead scientist sent one guard to go see what turned off the power and he sent another guard to check on SCP-████-2. Thirty seconds before we heard a loud crash and gunshots. Three more guards run down the hallway to the gunshot. I saw half of a torso get thrown down the hallway.I heard three more screams followed by silence. Then our lead scientist rushed to pull out his cell phone to tell the foundation about what happened and to order in the white wolves. The creature dug a hole through its cell wall to the outside then it proceeded to walk to the south. it took the white wolves three hours to find and subdue SCP-████-2.On ██-██-████ there were 7 fatalities and no one could figure out what caused the power outage. But thanks to that incident we have put the freezer on a separate power grid with a backup generator.
